VBA复制文件它不存在

Question

我有一个文件列表，分为两列 A 和 B。

• A 列是 B 的来源
• B 列是目标

下面的代码将文件从源复制到目标。但如果目的地存在，它会给我错误。条件是什么，如果它发现它存在，它不会做任何事情？

代码有什么问题？

  Sub FC_Copy()

Dim ClientsFolderDestination
Dim fso As New FileSystemObject
Dim rep_destination
Dim source

    lastrow = ThisWorkbook.Worksheets("XClients").Cells(Application.Rows.Count, 1).End(xlUp).Row

    For i = 5 To lastrow
        source = ThisWorkbook.Worksheets("XClients").Cells(i, 1).Value
        ClientsFolderDestination= ThisWorkbook.Worksheets("XClients").Cells(i, 2).Value
        If fso.FileExists(source) Then
            rep_destination = Left(ClientsFolderDestination, Len(ClientsFolderDestination) - Len(fso.GetFileName(ClientsFolderDestination)) - 1)

         If Not fso.FolderExists(rep_destination) Then
          sub_rep = Split(rep_destination, "\")
          myrep = sub_rep(0)
          If Not fso.FolderExists(myrep) Then
              MkDir myrep
           End If
           For irep = 1 To UBound(sub_rep)
              myrep = myrep & "\" & sub_rep(irep)
               If Not fso.FolderExists(myrep) Then
                    MkDir myrep
               End If
         Next
    End If

            fso.CopyFile source, ClientsFolderDestination
        End If
    Next i
end sub

试试这个。

1. 这不使用 Microsoft Scripting Runtime Library。
2. 它使用一个常用函数来检查文件和文件夹是否存在
3. 它适合诸如 C:\Sample.xlsx
之类的目标路径

代码

Sub FC_Copy()
    Dim ws As Worksheet
    Dim source As String, Destination As String, sTemp As String
    Dim lRow As Long, i As Long, j As Long
    Dim MyAr As Variant

    Set ws = ThisWorkbook.Sheets("XClients")

    With ws
        '~~> Find Last Row
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 5 To lRow            
            source = .Range("A" & i).Value
            Destination = .Range("B" & i).Value                
            MyAr = Split(Destination, "\")

            '~~> This check is required for destination paths like C:\Sample.xlsx
            If UBound(MyAr) > 1 Then
                sTemp = MyAr(0)                
                For j = 1 To UBound(MyAr)
                    sTemp = sTemp & "\" & MyAr(j)
                    If Not FileFolderExists(sTemp) = True Then MkDir sTemp
                Next j
            End If

            If Not FileFolderExists(Destination) Then FileCopy source, Destination
        Next i
    End With
End Sub

Public Function FileFolderExists(strFullPath As String) As Boolean
    On Error GoTo Whoa
    If Not Dir(strFullPath, vbDirectory) = vbNullString Then FileFolderExists = True
    On Error GoTo 0
Whoa:
End Function
